| # Puzzle-Map Dataset |
|
|
| The **Puzzle-Map Dataset** is a collection of images and annotations for research on computer vision applied to jigsaw puzzles. |
|
|
| ## Directory Structure |
|
|
| ```text |
| masks/ |
| *.png | *.jpg |
| |
| masks-raw/ |
| *.png | *.jpg |

|
|
| ## Description |
|
|
| * **masks/** – Processed masks used for data augmentation. |
| * **masks-raw/** – Original masks used to generate the processed masks. |
| * **pieces/** – Cropped puzzle piece images and their annotations. |
| * **puzzles/** – Complete puzzle images and their annotations. |
|
|
| > **Note:** This dataset does **not** currently provide segmentation annotations. The mask images are auxiliary data used for data augmentation. |
|
|
| ## Piece Annotations |
|
|
| Each image in the `pieces/` directory may contain one or more annotated puzzle pieces. The annotations are stored in `annotations.json`. |
|
|
| Each piece includes the following information: |
|
|
| * **Bounding box** |
| * **Image quality** (`valid`) |
| * **Piece rotation** |
| * **Side classification** (`INNER`, `OUTER`, `SMOOTH`) |
| * **Puzzle identification** |
| * **Puzzle row and column** |
| * **Piece angle inside the original puzzle** |
|
|
| Example: |
|
|
| ```json |
| { |
| "pieces": [ |
| { |
| "bbox": [xmin, ymin, xmax, ymax], |
| "valid": true, |
| "rotation": 90, |
| "sides": { |
| "top": "OUTER", |
| "right": "INNER", |
| "bottom": "SMOOTH", |
| "left": "INNER" |
| }, |
| "puzzle": { |
| "name": "puzzle_001", |
| "row": 3, |
| "column": 5, |
| "angle": 180 |
| } |
| } |
| ] |
| } |
| ``` |
|
|
| ## Acknowledgements |
|
|
| Part of the images and bounding box annotations included in the `pieces/` directory were built upon publicly available datasets from **Roboflow Universe**. |
|
|
| The original authors deserve full credit for collecting and publishing these datasets. |
|
|
| During the development of the Puzzle-Map Dataset, these original annotations were **extended** with additional information, including: |
|
|
| * Image quality labels (`valid`) |
| * Piece rotation |
| * Piece side classification (`INNER`, `OUTER`, `SMOOTH`) |
| * Puzzle identification |
| * Puzzle position (row and column) |
| * Piece orientation angle |
|
|
| These additional annotations were created specifically for the Puzzle-Map project. |
